Drinking water treatment with poly aluminium chloride.

The Use of Poly Aluminium Chloride in Drinking Water Treatment Introduction Poly aluminium chloride (PAC) is a widely used coagulant in water treatment processes due to its ability to effectively remove impurities and contaminants from water. It is particularly effective in treating drinking water, as it helps to ensure that the water we consume is safe and of high quality. In this article, we will discuss the various aspects of PAC and its role in drinking water treatment. Chemical Properties and Mechanism of Action PAC is a polymeric compound composed of aluminum ions and hydroxide ions. It acts as a coagulant by neutralizing the negative charges on the surfaces of suspended particles in water. This causes the particles to clump together and form larger aggregates, which can then be easily removed by sedimentation or filtration. Advantages of Using PAC in Drinking Water Treatment 1. High efficiency PAC is highly effective in removing a wide range of impurities, including suspended solids, algae, and bacteria, from water. 2. Cost-effective Compared to other coagulants, PAC is relatively inexpensive and easy to handle. 3. Environmentally friendly PAC is non-toxic and biodegradable, making it an environmentally friendly alternative to other coagulants. 4 4

poly aluminium chloride for drinking water. Versatility PAC can be used in various water treatment processes, including surface water treatment, groundwater treatment, and industrial wastewater treatment. Applications of PAC in Drinking Water Treatment 1. Pre-treatment PAC is often used as a pre-treatment step to remove suspended solids and other impurities from raw water before it is subjected to further treatment processes such as reverse osmosis or distillation. 2. Coagulation and Flocculation PAC is commonly used in conjunction with flocculants to improve the efficiency of sedimentation and filtration processes. The flocculants help to bind the PAC-coated particles together, forming larger flocs that settle more rapidly and efficiently. 3. Disinfection Although PAC itself does not have disinfectant properties, it can be used in combination with other disinfectants such as chlorine or ozone to enhance their effectiveness. Conclusion In conclusion, poly aluminium chloride is a versatile and cost-effective coagulant that plays a crucial role in ensuring the safety and quality of drinking water. Its ability to effectively remove a wide range of impurities and contaminants makes it an essential tool for water treatment plants around the world. As demand for safe and clean drinking water continues to grow, the use of PAC is likely to increase even further in the future.
